Gas Safe Engineers With Real Repair Experience
Not every boiler engineer is a boiler repair specialist. At Next Gen Boilers Ltd, all of our engineers have extensive diagnostic training and hands-on experience across all major boiler brands. We carry professional fault-code readers and a comprehensive stock of the most commonly needed parts on every van.
Over 10 years and 700+ repairs across Greater Manchester, we've seen virtually every boiler fault there is. That experience means faster diagnosis, higher first-fix rates, and less disruption to your home.
We're also honest when a repair isn't the right answer. If your boiler is old or the repair cost approaches the value of a replacement, we'll tell you straight — without any pressure to book work you don't need.
Our Commitment: No Unnecessary Repairs
We will never recommend a repair or replacement that we don't genuinely believe is necessary. Before any chargeable work begins, you'll receive a clear upfront quote. You are under no obligation to proceed. We earn our reputation through honesty — and 87 five-star reviews suggest that approach works.
Genuine 24/7 Emergency Cover
Our 24-hour emergency line is answered by a real person — not a call centre. When you call us at 2am in January, a qualified engineer will speak to you, assess your situation, and dispatch cover where it's needed. We don't operate a "next available appointment" emergency service.
Emergency line: 07305 687 331Common Boiler Problems We Fix
We carry an extensive range of parts for all major brands — the majority of these repairs are completed on the first visit. Fixed diagnostic fee from £89, deducted if you proceed.
No Heating or Hot Water
Complete loss of heating and hot water — our most common emergency call-out. Usually resolved within a few hours.
From £89
Boiler Losing Pressure
A slow pressure drop often indicates a small water leak or a failing pressure relief valve. Straightforward to diagnose and fix.
From £89
Pilot Light Keeps Going Out
Usually caused by a faulty thermocouple or a problem with the gas supply. Our engineers carry the most common parts on every van.
From £99
Boiler Making Banging Noises
Banging, kettling or gurgling sounds often indicate limescale build-up or a failing pump. Early intervention prevents more serious damage.
From £99
Radiators Cold or Not Heating Evenly
Air in the system, a failing pump, or sludge blockages are common causes. Usually resolved with a power flush or re-balance.
From £89
Thermostat Fault
A faulty thermostat can cause the boiler to not respond or behave erratically. We can diagnose and replace on the same visit.
From £79
Gas Leak Suspected
If you smell gas, leave the property immediately and call the Gas Emergency helpline. Then call us — we can make safe and investigate once the area is clear.
From £99
PCB or Ignition Fault
Printed circuit board and ignition faults are more complex — but our engineers are trained on all major makes and carry common PCBs in stock.
From £129
How Our Repair Process Works
A consistent, professional process — whether it's 2pm on a Tuesday or 2am on a Saturday.
Call Us or Book Online
Call 07305 687 331 any time — day or night — or use our online booking form. For emergencies we aim to have an engineer with you within 3 hours. For non-urgent repairs we can usually attend the same day or next morning.
Diagnostic Visit & Honest Quote
Your Gas Safe registered engineer will arrive, carry out a full diagnostic assessment of your boiler, and give you an honest upfront quote for the repair. The diagnostic fee starts at £89. You'll never be pressured to proceed.
Repair Carried Out — First Visit Where Possible
Our vans carry an extensive range of parts for all major boiler brands. In the majority of cases, we can complete the repair on the same visit. If a part needs ordering, we'll get it to you as quickly as possible — often next day.
Full System Test & Safety Check
Once the repair is complete, we carry out a comprehensive test of the entire system — not just the repaired component. We check gas pressure, flue operation, safety devices and controls before declaring the boiler safe for use.
Report & Advice
We'll explain exactly what caused the fault, what we did to fix it, and whether there are any underlying issues to be aware of. If the repair is no longer economic, we'll give you an honest assessment and quote for replacement — without any pressure.

What Our Customers Say
4.9 stars from 87 verified reviews · Google & Checkatrade
"Boiler stopped working at 10pm on a Saturday in February. Called Next Gen and an engineer was at my door by 1am. Diagnosed a faulty PCB, had the part on the van, and the heating was back on by 2:30am. Exceptional service."
"I'd been told by another company I needed a new boiler. The engineer from Next Gen took one look and said it was just a faulty diverter valve. £130 repair instead of a new boiler. Honest, professional and saved me a fortune."
"Called at 8am with no heating and no hot water in January. Engineer arrived by 11am, diagnosed and fixed a pressure relief valve issue within the hour. Clear pricing upfront and no nasty surprises."
"My elderly mum's boiler broke down and Next Gen had her sorted the same afternoon. The engineer was brilliant with her, explained everything clearly and made sure she was warm before he left. Couldn't ask for more."
Repair FAQs
Common questions about our repair service
How quickly can you get to me in an emergency?
For genuine emergency call-outs across Greater Manchester, we aim to have an engineer with you within 3 hours. In most cases, for calls received before 6pm, we can attend the same day. We operate 24 hours a day, 7 days a week, 365 days a year.
What does the diagnostic fee include?
The diagnostic fee (from £89) covers your engineer's travel, a full assessment of your boiler, fault diagnosis using professional equipment, and an honest quote for any repair work. If you proceed with the repair, this fee is deducted from the total cost.
Can you fix my boiler in one visit?
In the majority of cases, yes. Our engineers carry an extensive stock of parts for all major boiler brands. For common faults — pressure issues, ignition problems, diverter valve failures, thermostat faults — we almost always complete the repair on the first visit.
What if my boiler is beyond repair?
We'll always tell you honestly if we believe a repair isn't economical or safe. If replacement is the better option, we'll give you a no-obligation fixed price for a new boiler installation — often available the very next day.
Do you repair all boiler brands?
Yes. Our engineers are trained on all major UK boiler brands including Worcester Bosch, Baxi, Viessmann, Ideal, Vaillant, Glow-worm, Potterton, Intergas and more. We carry diagnostic readers for most makes and common parts for the most popular models.
Is there a call-out charge?
There is no separate call-out charge. Our diagnostic fee (from £89) is an all-inclusive fee that covers the visit, diagnosis and your repair quote. If we can't diagnose the problem or the fault is unclearable, we'll be honest with you before charging.
Do you offer a warranty on repairs?
Yes. All repair work carried out by Next Gen Boilers Ltd is covered by a 12-month workmanship warranty. Any parts fitted are covered by the manufacturer's parts warranty, which varies by component but is typically 12 months.
My boiler is old — is it worth repairing?
Generally, if your boiler is over 15 years old and requires a major component (heat exchanger, PCB, burner), replacement is usually more economical in the long run. For newer boilers or minor repairs, fixing is almost always the right decision. We'll give you an honest assessment either way.
